and some other Genera of Malayan Plants. 125 
Oss. I am not aware that these two plants have been described 
by any botanist since the time of Rumphius, or that any 
conjecture has been made regarding their place and family 
from his figure or description. From their common habit 
as parasites, I should have been much inclined to place 
them under one genus; but the different number of seeds 
in each, supported by the difference of a simple and bifid 
stigma, seems to oppose this, while the distinction is further 
confirmed by the different disposition and insertion of the 
leaves, which in Hydnophytum are arranged precisely as 
usual in the Rubiacee, but in Myrmecodia are crowded round 
the thick fleshy branches in such a manner, that their being 
really opposite is not immediately apparent, while their 
insertion on their broad peltate bases is further peculiar. 
LASIANTHUS. 
Rubiacee. Juss. 
Calyz 4-partitus, laciniis linearibus. Corolla infundibuliformis, 
pilosa. Stamina 4. Stigmata 4, linearia, crassa. Bacca 
tetrapyrena. 
Suffrutices, floribus axillaribus, bracteis oppositis, baccis cyaneis. 
LASIANTHUS CYANOCARPUS. 
Villosus, bracteis magnis cordatis. 
Found at Tappanooly on the west coast of Sumatra. 
Stem herbaceous or suffrutescent, erect, round, villous. Leaves

lous; three or three inches and a half long. Petioles short. 
Stipules interpetiolar, acute. Flowers generally three in each 
axil, nearly sessile, supported by two large opposite cor- 
date bracts. Calyx superior, four-, sometimes five-parted; 
laciniæ linear, acute, pilose. Corolla yellow, tubular, funnel-
